When I got mine, it was the only copy they had, so you might want to call ahead to reserve one to save a wasted trip.

The double mode works as advertised on the DSi. The song mode is much improved as it allows synth changes when playing now, and tracks can be muted as a pattern. Synth parameters are the same.

Gamestop is offering a $99.99 upgrade to the DSi XL from the DSi, or $129.99 from the DS lite. Retail price of the DSi XL will be $189.99. I plan to compare the audio quality of the DSiXL vs. the DSi when a demo is available in a store to test.

It still has 100 patterns in song mode, but in dual mode, you can chain each "side" of the song to give 200 patterns. The song sequencer can play A, B, or A-B chained, plus each step can play and mute any part on both sides simultaneously. In other words, you now have 32 patterns to choose from for each song step, with any part playing or muted. However, each song step plays only one pattern # at a time, such that if you pick pattern #1, for example, then you are playing pattern #1A and #1B as a pair together. You can't play pattern #1A and #2B at the same time.

Still, the song mode is a big improvement for the DS10+. The ability to modify synth parameters and other things while the song is playing is great.

You have to save and load each side (A & B) separately to different memory slots. Dual mode is somewhat confusing because of how it's done - you have to always be aware of what side you're using at any instant.

I'm thinking I'm going to want the DSiXL because the screen size is more adaptable to performing live with Korg DS+

I was thinking I'd wait until those who buy the DSiXL will eventually tire of it and then want the smaller one. Used gear is as good as new, just cheaper._________________Korg PX5d
